Protistor® High-Speed Cylindrical Fuse (10×38 mm) with 2.5A and 690VAC rating, offering full-range gR protection for semiconductors and power electronics.
£5.36
The Mersen FR10GR69V2.5 is a compact, high-performance ultra-fast semiconductor protection fuse designed to protect sensitive power electronic equipment against damaging overcurrent and short-circuit conditions. Manufactured by Mersen, this cylindrical fuse combines rapid fault interruption with dependable electrical performance for industrial power conversion and control applications.
Featuring a gR utilisation category, the FR10GR69V2.5 provides full-range protection for semiconductor devices. Its ultra-fast operating characteristics help limit peak current and let-through energy during a fault, reducing the risk of damage to diodes, thyristors, rectifiers, inverters and other sensitive electronic components.
With a rated current of 2.5 A and a maximum rated voltage of 690 V AC, this fuse is suitable for low-current semiconductor circuits operating at demanding industrial voltages. Its standard 10 × 38 mm cylindrical format enables straightforward installation in compatible fuse holders and compact electrical assemblies.
Semiconductor devices can be damaged by fault currents within a very short period. The Mersen FR10GR69V2.5 is engineered to interrupt faults rapidly and restrict the amount of electrical energy that reaches protected components. This helps reduce thermal and mechanical stress while supporting reliable operation of power electronic equipment.
Its gR full-range characteristics provide protection against both overload and short-circuit currents. The fuse is therefore well suited to industrial systems where sensitive semiconductor components require faster and more precise protection than conventional general-purpose fuses can provide.
